Large HP XC Cluster of Server Blades

Figure 2-3 (page 37) illustrates a large HP XC cluster of eight regions, with 32 enclosures per region.

There is a Gigabit Ethernet switch for the HP XC system that is connected to a Gigabit Ethernet switch in each region.

The Gigabit Ethernet switch in a region is connected to each enclosure's Gigabit Ethernet switch in bay 1 and to a ProCurve 2650 switch. The ProCurve 2650 switch is connected to the Primary Onboard Administrator External Link of each enclosure.
